As the old saying goes, a picture is worth a thousand words. Often times, in our various articles, we only explain how to use resources through words. In order to facilitate the reader, we decided to now add a new dimension to Resource Mania: screencasts. These video presentations will add simple visual aids and help to explain the use of new tools.
In today’s 3 minute screencast, we present regular expressions libraries. This following tutorial will take you through the process of entering a library, finding the necessary code, and implementing it directly into PHP. Once you have viewed this tutorial, we hope that you will understand how to validate data through regular expressions.
